EN16080Theoretical study of the hydrolysis of HOSO+NO2 as a source of atmospheric HONO: effects of H2O or NH3
Environmental context. Nitrous acid (HONO) has long been recognized as an important atmospheric pollutant, with the reaction of HOSO + NO2 being a source of HONO. We explore the effects of an additional water or ammonia molecule on this reaction. Calculations show that the ammonia molecule has a more effective role than the water molecule in assisting the reaction.
